Embodiment 1
[0038] 0.5g p-benzoquinone is dissolved in acetone to form an acetone solution whose mass fraction is 80% p-benzoquinone, and the catalyst Pd / RuO 2 / TiO 2 The molecular sieves were impregnated in the acetone solution of p-benzoquinone for 2 days, then taken out and put into the autoclave. Seal the high-pressure reaction kettle, pump out the air in the kettle to make the vacuum degree 0.1MPa, and pass the cooling liquid (0°C, ethylene glycol) in a constant temperature cold bath. After the temperature in the kettle is lowered to 0°C and stabilized, open the hydrogen inlet valve , adjust the pressure in the kettle, adjust the pressure to 1MPa (P 1 ), stop the hydrogen flow, turn on the light source, so that the inside of the high-pressure reactor is in an environment with light and catalyst. After the pressure is stabilized, 0.3MPa(P 2 ), the organic hydrogen cage compound is completely generated, the light source is turned off, and the hydrogen storage ends. The hydrogen sto...
Embodiment 2
[0041] Dissolve 1g benzaldehyde in acetone solution, its mass fraction is 50%, will be loaded with anatase type TiO 2The molecular sieve of the catalyst is impregnated in the acetone solution of benzaldehyde, taken out after impregnated for 3 days, and put into a high-pressure reactor. Seal the high-pressure reaction kettle, pump out the air in the kettle to make the vacuum degree 0.3MPa, and pass the cooling liquid (5°C, ethylene glycol) in a constant temperature cold bath. After the temperature in the kettle drops to 5°C and stabilizes, open the hydrogen gas inlet valve , adjust the pressure in the kettle, adjust the pressure to 10MPa (P 1 ), stop the hydrogen flow, turn on the light source, so that the inside of the high-pressure reactor is in an environment with light and catalyst. After the pressure stabilizes, it is 2.5MPa(P 2 ), the organic hydrogen cage compound is completely generated, and the hydrogen storage ends when the light source is turned off.

Embodiment 3
[0045] 0.5g benzophenone is dissolved in acetone, forms the benzophenone acetone solution that mass fraction is 60%, load-type ruthenium catalyst (Ru / γ-Al 2 o 3 ) molecular sieves were impregnated in the acetone solution of benzophenone, impregnated for 2 days, taken out and put into the autoclave. Seal the high-pressure reaction kettle, pump out the air in the kettle to make the vacuum degree 0.4MPa, pass the liquid (20°C, ethylene glycol) in a constant temperature cold bath, and wait for the temperature in the kettle to drop to 20°C. After stabilization, open the hydrogen gas inlet valve, Adjust the pressure in the kettle to adjust the pressure to 20MPa (P 1 ), stop the hydrogen flow, turn on the light source, so that the inside of the high-pressure reactor is in an environment with light and catalyst. After the pressure stabilizes, it is 6.8MPa(P 2 ), the organic hydrogen cage compound is completely generated, the light source is turned off, and the hydrogen storage ends...
